Factors Affecting the Performance of Varieties Released Recently in the South African Sugar
نویسنده
چکیده
There are several areas in the South African sugar industry where the ubiquitous variety, NCo 376, is beingsuperseded by newer varieties. Growers have a choice of varieties which have outyielded NCo 376 in trials under a wide range of conditions. There are others which have yielded more than NCo 376 in certain conditions. It is opportune to report the results of trials that have been conducted to investigate the agronomic characteristics of the recently released varieties. The main factors which influence the yield of one variety relative to another are fluctuations in soil moisture, season and age at which the cane is harvested, soil type, pests and diseases. Some of these factors have been deliberately varied in variety trials while the effects of others have been deduced by comparing the results of different trials. .

Initial sugarcane production in South Africa relied on imported varieties. When imported varieties succumbed to diseases, the industry established the South African Research Institute (SASRI) with the mandate to develop sugarcane varieties. The popular and highly successful varieties, NCo310 and NCo376 were selected from crosses imported from India. NCo310 and NCo376 were grown successfully in ...

Varieties NCo376 and N14 are the most widely grown varieties in Zimbabwe and are used as control varieties in the selection programme. The success of NCo376 was due to its high yield potential throughout the year and its ability to maintain good yields, even in advanced ratoons. A study was done to compare the performances of N14 and NCo376 in the South-East Lowveld of Zimbabwe, using data from...
متن کاملThe Effect of Ratoon Stunting Disease on the Yield of Some South African Sugarcane Varieties under Irrigated and Rainfed Conditions
The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...
